No HD channels found

Today I bought a HDR-FOX T2 to replace my PVR9300T, but quickly found a problem:

No HD channels were tuned in by the set-up wizard. The HDTV Group is empty. At the same time the TV's internal tuner, still connected via Antenna Out, receives an excellent strong HD signal.
(Crystal Palace transmitter is about 5km away and we had good roof-top aerial installed when the PVR was purchased in 2009).

I had exactly the same thing when I first tried to [manual] tune my Humax. I hadn't realised that the HD channels required the transmission type to be changed from DVB-T to DVB-T2. Would have thought the set-up wizard should pick this up but who knows?

That seems very strange. Follow the instructions for manual tuning HERE (click), and note that you need to select "DVB-T2" for the HiDef multiplex.

Thanks, Black Hole, just finished that with disappointing results. C22, C23, C25, C26 and C28 (DVB-T) all found channels but C30 (DVB-T2) gave error message No Channels Found. The options for Bandwidth on C30 remained at 8k and 7k, is this correct?
...and the TV's tuner still gives excellent HD reception!

Yep, looks to me like its being boosted by the other equipment. The HDR does need a good signal to tune in to.
Your aerial might have become slightly mis-aligned since it was installed.. or could be being blocked by something.
